act description, re erence being had to the accompanying drawings, which form a part of' this specification.

The object of my invention is to provlde an apparatus adapted to straighten pipes in a simple, effective and expeditious manner.

In the drawings: Figure 1 is a side elevation of the apparatus; Fig. 2 is a front elevation partly in section; Fig. 3 is a plan of the roll bed.

a is the roll and b the roll bed. The bed b is stationary and its upper surface is spaced from, and concentric with, the periphery of the roll a. The shaft of the roll rotates in bearings c and is driven from a shaft to which it is connected by means of a universal joint d. The roll bearings c are slidable in pedestals e to which are bolted caps f. Secured to and extending upward from the roll bearings c are hangers g. The upper ends of the hangers are threaded to receive nuts h. Springs c' are confined between nuts h and caps f.

7c is an endless delivery conveyer, the same comprising a sprocket chain having flights Z between which the pipes are carried. One end of the delivery conveyer is shown as passing around a ydriving sprocket wheel m.

n is a delivery chute between the discharge end of the delivery conveyer and the side of the roll bed. This chute has a downwardly extending flange secured to the side wall of the roll bed b. i

0 is an endless discharge conveyer similar in construction to the delivery conveyer and driven from the sprocket wheel p.

1' is a discharge 4chute between the receiving end of the discharge conveyer and the side 'of the roll bed. This chute also has a downwardly-extending flange secured to the side of the roll bed.

Arranged over the roll a is a line of pipe s extending longitudinally of the roll and having perforations through which water is discharged from the pipe evenly along and upon the roll. The roll bed b is providedwith slits or perforations through which the water and scale are discharged. By adjusting the nuts z. the distance between the roll a and the bed I) may be varied from one quarter of an inch to four inches dependent upon the diameter of the pipe to -be straightened. The pipes are delivered, while they are yet hot from the size rolls, to the `delivery conveyer 1c, whence they are discharged onto the chute n and thence pass into the space between the roll a and the bed Z). The roll a transfers the pipes from one side to the other of the bed l). During the passage of the pipes between the roll and its bed they are repeatedly turned about their axes and eventually straightened. They are finally discharged onto the chute r and thence pass to the discharge conveyer 0.

Having now fully described my invention, what I claim and'desire to protect by Letters Patent is:

1. In a pipe straightener, the combination with a horizontally arranged roll and means to rotate the same7 of bearings in which the roll rotates, means for spraying water upon the roll, a concave roll bed, arranged beneath the roll, having perforations through which the water and scale are discharged, and pedestals in which the bearings are freely movable vertically so as to permit the pipes to pass between the roll and bed under the yielding pressure of the roll.

2. In a pipe straightener, the combination with a roll, of bearings in which the roll shaft rotates, pedestals in which said bearings are vertically movable, ca s secured to the pedestals, hangers exten ing upward through the caps, nuts threaded on the hangers, springs confined between the caps and the nuts, and a concave roll bed arranged beneath the roll.

3.

MOON. convey away the pipes discharged from bel Witnesses: 5 tween the roll and bed. K. R. WAGNER,
